Specification forming part of Letters Patent No. 121,651, dated December 5, 1871.

To alll whom it may concern:

Be it known that I, GEORGE Norwich, in the county,T of New London and State ot Connecticut, have invented a certain new and uset'ul Improved Method ot' lnlayin g Plastic Ma.- terial with colored plastic material t'or forming blocks for pavements, t-iles, and other articles; and l do hereby declare that the following is a t'ull, clear, and exact description of the same, sufticient to enable others versed in the art to make and use the same, reference being had to the accompanying drawing forming part ot' this specitication.

ln the drawing, Figure 1 is a perspective view ot' an improved metallic inlaying-mold which is employed to t'orm recesses ot" dilerent contour in plastic blocks. Fig. 2 is a plan view ot' a portion otl a pavement, showing a single block having the recess formed prepai'atoi'y to inlaying, the inlaying-mold being in place, shown in dotted lines. Fig. 3 illustrates the inlaying-mold, having angular lips or t'ormers, for forming the sides ot' the recess in blocks so as to produce angular tigures when the inlaying medium is applied. Fig. -L is a plan view ot' a portion ot a pavement, showing one ot' the blocks having a star recess formed therein preparatory to receiving the inlaying material. Fig. 5 is a perspective View, showing the inlaying-mold made up in one body. Fig. (i is a top or plan view ofthe mode ol'jointing inlaid blocks composing a paven'xcnt; and Fig. 7 is also a plan view ot a design for an inlaid pavement similar in construction to that shown in Fig. l.

lhis invention consists in the construction and employment ot' inlaying-n'iolds which are provided at one end, on its top surface, with a handie or shield, and on the other cud and opposite. side ot sa-id plate with a depending cutter or cutters, which are shaped into varied forms, so that when forced down into a plastic block and the inclosed plastic mass removed the recess thus formed in said block will in outline represent the ligure desired to be produced. lhe invention further consist-s in inlaying a figure, body, or block, or a series ot blocks composing a pavement, t'ormed ot' concrete or a similar substance, while the same are in a plastic state or condition, and in position with a colored plastic concrete or material of the same or of different ingredients to that to which it is applied, by mea-ns ot' inlay- H. MOORE, of

in g molds, in such a manner that when the inlaying medium is applied to the said concrete ligure, body, block, or blocks, the two will cohere or unite and form a solid homogeneous mass. The invention tin-ally consists in iniaying a plastic concrete block or article, at'ter it has been formed, in its destined position, with a colored plastic concrete by means ot' inlaying molds, so that the inlaid medium will represent ligures of ditterent shape or contour, and which inlaid tigures may be raised or depressed, or otherwise ornamented, or itseltl be again inlaid.

In the dragring, A designates inlaying-im'ilds. These molds are formed otA any suitable sheet or cast metal, and, il' sheet metal be used, are preferably struck up in one piece. The body c is provided on its top surface with a vertical handle, b, by which the. device is lifted, and which also acts as a shield, for a purpose hereinafter mentioned. From the under side otl these met-al iulayin g-molds depend one or more molds, c, which are. either ot an angular, curved, square, or straight t'orn'iation, so that when the body A of the inlaying-mold is laid uponone or more of the plastic blocks when in position, and the said lnold or molds c l'orced down into the. said plastic block or blocks, and the mass thus surrounded removed, the cavity or space thus formed will represent in outline the design or shape ot the figure intended to be produced. 'lhe molds c are made ol'auy external l'orm or shape, and may be made. in sectimis with the body A and handle or shield ll, as shown in Figs. l and Ii, and the several parts required to produce thc t'ull design or tigurc locltcd or secured in position; or the mold may be made inone piece with the body i. and handle or shield (l, as shown in Figz, which is preferable. B B rcpr se11t blocks ot' concrete or similar substance. laid in. the usual or ordinary manner, and in position either with or without a separable ,ioint between them.

l`o inlay one or all ot these concrete blocks while the same are in a plastic state 0r condition and in position with a coloring plastic concrete with the same or with dil'l-rcnt ingredients from that composing the plastic biot-lt l place the iulaying-mold upon the plastic blocks already in position und torce thc mold or molds v, having the desired i'orm or ligure, down into the plastic block or blocks-say, about one inch, more or lessand then remove the mass thus surrouiuled,

as clearlyshown in Figs. 2 and Ll, which removed l mass is used again in formingl partJ ot' another l block. The space or cavity produced by such l removal while the molds are still in posit-ion I lill with ay plastic mass ot' any desired color and eamposition, the molds being` cz'irefully riunored by taking` hold ot' the handle l), the slight space or opening' lett being, closed by gentle, pressure upon the surface ofthe plastie block and the plastic inlaid material. NVhile. these blocks, tiles, or articles are arranged in their destined position, and are yet in their salt or plastic state, I inlay or insert into the same a previously-prepared figure or ornament ot any shape, design, color or colors, or composition, so that when the said plastic block or article has becomeI hard the tie'- ure or ornament will be snugly and firmly held in position and the block or article thus inlaid will present an appearance as it' it was an integra-l part.

In Figs. 6 and 7 I show the plastio blocks laid in position so as to exhibit the manner ot' join!- ing, inlaid lm-veinents, I first mold in the i ordinary manner, in position, the square block t); i then, it' I inold the plastic block l) or l) l?, the j dotted lines ip/"will showlhe, yioints ol" separation. l W'hen these blocks are. in this position and in a soft or plastic state l inlay them with colored plastic material at the separating-iolnts c /l In this ease the iulayine or design l'ormed will be crossed or intersected by the said separatine'- joint. To dispense with this joint I cut. ont or l mold the plastic block, `when in its molded posiA tion, wit-l1 a recess, g .ff, ot' an outline correspond` ingl to the outline ot the. design or ligure to be inlaid. The said blocks are marked or laid oli' in diamonds or squares, as shown by lilies i,

, and either or every alternate one, while in its plastic state, and molded position, is inlaid with the plastic mass otI the Color and composition desired.

l. intend, as stated above, withoutdeparture from the spirit-ot' my invention, to inlay or insert a previously-i:repared hard ligure or or mment ot' any desired color or colors and composition in the plastic bloeit, tile, figure, or article while the latter is in its plastic state and molded coudition.

rI"he ioints between any or all ot' thel blocks, tiles, or figures, or between the inlaid material and the block or article into which it is inserted or inlaid, may be made. so as to be separable by the employment ot'powdered steatite or its equivalent..

llavint;` t-hus described my invention, what. l claim as new7 and desire to secure by Letters latent. is-

l. Inlayiue' a plastic block-otconcrete in the position in whieh it is to remain with a colored plasticl material.

2. lnlayinf; a plastic concret-e block while in position with a colored plastic material, in the manner and by the means substantially as described.

J3. lnlayingor insertiner a previously-prepared ligure or ornament into a plastic bloeh ol' eoni crete molded in the position in which il is to remain.
